In the case of the GWH4 and 6, press the textured buttons on each side of the 
headshield and ease the lens forward, unclipping it from the buttons. Reverse 
the process to replace or re-fit. Due to the small size of the components, the 
lithium battery cannot be replaced.

The cartridge can be wiped with a household glass cleaner when dirty. Apply 
the cleaner with a clean cloth or paper towel. DO NOT USE ALCOHOL TO 
CLEAN. DO NOT APPLY CLEANER DIRECTLY TO THE CARTRIDGE.

Clean all lenses with a soft tissue and suitable lens cleaning fluid. Do not use 
solvents. Never use tools or other sharp objects to remove material from the 
lens or screen. This may cause damage which may cause incorrect function 
and invalidate the warranty. Store the unit in it’s box or similar safe place.
